UNR511L00L

Overview

The UNR511L00L is a Silicon PNP epitaxial planar transistor with built-in bias resistors, designed for digital circuits. It features an S-Mini (SC-70) package with three terminals: Base, Emitter, and Collector. The device operates with a collector-emitter voltage of -50 V and a maximum collector current of -100 mA. Internal resistance values are R1 = 4.7 kΩ and R2 = 4.7 kΩ. Key electrical characteristics include a minimum forward current transfer ratio (hFE) of 20 and a typical transition frequency (fT) of 80 MHz.

Feature Summary

• Integrates two bias resistors to reduce component count and equipment size
• Utilizes an S-Mini surface mount package for automated insertion

Applications

• Digital logic interface circuits
• Switching applications in consumer electronics
• General-purpose signal control

Procurement Notes

Verify the specific ordering suffix against official Panasonic documentation to confirm exact resistance tolerances and hFE binning. Confirm RoHS compliance status and lifecycle stage through authorized distributors or the manufacturer's website before finalizing procurement plans.

Selection Notes

Select this component when a compact PNP transistor with fixed base biasing is required. Ensure the circuit design accommodates the negative voltage polarity inherent to PNP devices. Verify that the integrated resistor values align with the specific drive requirements of the connected logic gates.

Part Context

This part belongs to the UNR511x Series, which comprises various PNP transistors with different internal resistor configurations. The series is engineered to simplify digital circuit designs by replacing discrete biasing networks with a single integrated component.

Replacement Considerations

Direct substitutes within the UNR511x series must be selected based on matching resistance ratios and hFE rankings. Cross-referencing datasheets for identical package dimensions and absolute maximum ratings is essential for pin-compatible replacements.
